Frolov Device: Main Physiological Effects
There are various effects related to hypercapnic hypoxic training
during and after application of the Frolov breathing device therapy.
It is easy to notice that sick people are generally chest
breathers. Chest breathing reduces oxygenation of the arterial blood
because lower portions of the lungs do not get new oxygen supply. (This
and other additional abnormal effects of chest breathing are described
in detail on the web page Chest
Breathing Problems, Tests and Solutions). Generally, people switch
to diaphragmatic unconscious breathing at rest, when their morning CP
is about 30 seconds or more. Regardless of the health state and other
details, Frolov device breathing sessions are done with strictly
diaphragmatic breathing. Diaphragmatic breathing leads to numerous
beneficial effects described above.
For people without ventilation-perfusion mismatch (over 80% of the
Higher CO2 in the alveoli of the lungs increases CO2 content in the
arterial blood. Since CO2 is powerful vasodilator (some research
articles claim that it is the most powerful known vasodilator),
breathing sessions improves blood supply to all vital organs of the
human body. Additional CO2 also enhances the Bohr effect (more oxygen
will be released by red blood cells in tissues). Since breathing
exercises are done while using the diaphragm, most people will get
immediate improvement in the oxygenation of the arterial blood (most
modern people are chest breathers and, even though they overbreathe,
their heavy chest breathing reduces oxygenation of the arterial blood
since lower parts of the lungs do not participate in gas exchange.)
Improved cell oxygenation reverses tissue hypoxia and generation of
free radicals due to anaerobic energy production mechanism in cells’
mitochondria. This normalizes the work of the immune system (less
cellular damage to repair). Additionally, improved metabolism of
proteins and amino acids, normalizes production of the immune cells.
Most importantly, since the breathing session can last up to 15-20
minutes, the breathing centre adapts to slower (less) breathing causing
long-lasting increase in arterial blood CO2 content (for many hours
after the session).
For people with ventilation-perfusion mismatch (severe asthma,
COPD, emphysema, etc.)
These groups of patients have too high CO2 level in the arterial
blood due to their main problem: dysfunctional alveoli that do not
participate in gas exchange. The main physiological problem for them is
insufficient oxygenation of the arterial blood and, as a result, too
low level of oxygen in cells of the brain, heart and other vital
organs. (Hence, these patients are among the first candidates for
breathing supplemental oxygen 24/7).
Breathing through the device increases their CO2 content in the
alveoli and airways (bronchi and bronchioles). Since CO2 is a powerful
natural bronchodilator and breathing exercises are done with gentle
mechanical stretching of the whole lungs (deep diaphragmatic breathing
through the device with maximum inhalations and exhalations), the
number of their alveoli that participates in gas exchange increases.
Therefore, these patients can use finger or pulse oximeters to confirm
that their blood oxygenation increases during and after a breathing
The main physiological effect of the breathing exercises for these
people is improved lung functions and better oxygenation of the
arterial blood. This leads to quick reduction in symptoms of their main
disease, increased energy, improved focus, sleep, digestion and many
other physiological and biochemical parameters. Their easier and
lighter breathing will last for many hours due to the adaptation of the
breathing centre to slower and more relaxed breathing.
The easiest way to measure the efficiency of the Frolov breathing
device therapy is to measure and compare the initial and final CPs.
Measure your CP just before the session and 1-2 min after finishing it.
Practical experience suggests that the Frolov breathing therapy is
superior to Buteyko breathing exercises by about 50-80%. Such advantage
is possible due to variety of factors: mainly increased dead volume,
large amplitude of diaphragmatic movements, and presence of positive
resistance pressure during exhalation, all of which help to achieve
higher CO2 concentrations in the alveoli of the lungs.
It is reasonable then, that the daily log for the Frolov breathing
therapy exercises includes the initial and final CPs, as the key
measured parameters of success. Most, but not all students also
experience a significant and immediate reduction in heart rate, while
the pulse gets lower later for other students.
In my view, the Frolov device is probably the most efficient known device
for breathing exercises. Solidly based on Buteyko's theory of
chronic hyperventilation and alveolar hypocapnia as foundations of many
chronic diseases, the Frolov device combines best features of the
Buteyko reduced breathing exercises, pranayama (from Hatha Yoga), PowerLung and
pursed-lip (resistive) breathing.
Breathing exercises can cause powerful cleansing reactions and can be dangerous for
pregnant women, people with organ transplants, GI problems, and panic attacks, as well as those who take medication
for diabetes, hypertension, hypothyroidism, and other conditions.
